AST SpaceMobile and our global partners are building the first and only space-based cellular broadband network to be accessible by standard smartphones. Called SpaceMobile, this ultra-powerful network is being designed to provide connectivity at 4G/5G speeds everywhere on the planet – on land, at sea and in flight. About the role We are seeking a highly motivated and detail-oriented Mechanisms Engineer to support the assembly, integration, and testing (AIT) of spacecraft mechanisms. The candidate will work hands-on in a dynamic environment, collaborating closely with design, test, and production teams to ensure successful build, qualification, and delivery of space mechanisms and subsystems. Responsibilities Provide manufacturing and test engineering support to Production during build, integration, and verification phases Perform and lead mechanism-level and subsystem-level tests; develop testing requirements, materials, processes, and tooling (vibration, shock, TVAC, assembly) Participate in and execute design, analysis, and system trade studies to determine mechanism AIT strategies at system and spacecraft levels Provide inputs to Design Engineering to optimize manufacturing flow, cost, and layout Prepare detailed product and process reports by collecting, analyzing, and summarizing data Execute design and analysis using sound engineering principles while adhering to company standards and program requirements Troubleshoot and investigate anomalies and failures, perform root-cause analysis, and drive resolution Participate in iterative mechanism design improvements based on findings in test and production Requirements Bachelor’s degree in mechanical or aerospace engineering Requirements Minimum of 2–5 years of relevant experience in aerospace or precision hardware assembly/test. Nice to have Experience with space-qualified mechanisms (e.g., release devices, actuators, hinges, latches, deployment systems) Familiarity with root cause and corrective action (RCCA) methodologies and nonconformance resolution Working knowledge of ECAD/MCAD integration, configuration control, and product data management systems Experience supporting vibration, shock, and TVAC test campaigns Understanding of cleanroom practices and contamination control Preferred certifications: IPC-A-610/J-STD-001, NASA-STD-8739 or ECSS-Q-ST-70 standards, AS9100, Six Sigma Requirements Strong interpersonal skills with the ability to collaborate across engineering and production teams Proven problem-solving mindset and ownership mentality Meticulous attention to detail to ensure accuracy of documentation and project deliverables Proactive, organized, and able to manage multiple priorities simultaneously Technology Stack CAD Tools: AutoDesk Inventor, SolidWorks, NX, or Creo Analysis Tools: FEA experience is a plus Data/Documentation Systems: Fusion or equivalent PDM/PLM tools General Tools: Microsoft Office Suite (Word, Excel, PowerPoint, Project) Test/Data Acquisition: LabVIEW or similar systems (preferred) Physical Requirements Capable of working hands-on with flight hardware, test setups, and precision instruments Ability to lift and move up to 25 lbs Availability for occasional extended shifts Night shift/weekend shift availability This job description may not be inclusive to the duties and responsibilities listed. Additional tasks may be assigned to the employee from time to time or the scope of the job may change as needed by business demands.
